问题
选择题
–--I play high-temperature Yoga in the gym every Sunday.
---- Good habit, but the air in the gym is bad ________.
A．to be breathed
B．to breathe
C．breathing
D．being breathed
答案
答案：B
本题考查非谓语动词。breathe和air之间虽然是动宾关系，但在主系表结构中,当表语形容词为good, light,heavy, difficult等时,其后常用不定式作状语,表示时间,原因,结果等,且常用主动形式表示被动意义。
